Don Winslow of the Navy #20

Don Winslow discovers Nazi prisoners being held on an island and engages them in combat, successfully taking them by surprise. After a brief battle, Winslow sends out a launch to bring in the captured German sailors and locates hidden camouflaged enemy planes in the brush. With his boat wrecked but luck holding out, Winslow spots a bomber and boards it to check the controls. That evening, as part of an entertainment show, Winslow exposes Nazi saboteurs and spies who had infiltrated the base by revealing their plan to change the commanding officer's plans and sabotage the Navy's operations.
